HORSESHOE ATTACHMENT.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, ALFRED F. MARTINS, a citizen of the United States, residing at New York city, in the county and State of New York, have invented new and useful Improvements in Horseshoe Attachments, of which the following is a specification.

This invention resides in certain features of construction set forth in the following specification and claims and illustrated in the annexed drawings. in which Figure 1 is an under view of a horseshoe with an attachment embodying this invention. Fig. 2 is asection along 00 m, Fig. 1. Fig. 3 is a section along 3/ Fig. 1. Fig. 4 is a detail view of a calk. Fig. 5 shows a shoe provided with a continuous calk according to this invention. Fig. 6 is a section along 2 a, Fig. 5.

Inthe drawings the letter a designates a horseshoe which may be of any size and of suitable shape to fit the animals foot. The under face of this shoe is provided with the toe-calks Z) 7) and the heel-calks b 6, respectively. Each set of the calks are secured to the shoe by means of the toe-clamp 0 and the heel-clamp (Z, respectively. The calks are inserted into slots 0 and d in the heel-clamps and toe-clamps and can be removed from the clamps when necessary. The toe-clamp is adjusted by means of a screw 6, having a nut f, and the latter when rotated on the screw either loosens or tightens the clamp. When the clamp is tightened, the tongue of the calk is pressed onto the inner rim of the shoe, thus securely holding the same in place. Each heel-clamp is also adjustable, and this is accomplished by means of a double-acting or right-andleft screw '9, which can be turned or rotated by head or capstan g to contract or expand the clamps. It will be seen that the calks can be adjusted to any thickness of shoe. The faces of the calks could be provided with spikes, rubber, or felt or other antislip material to prevent slipping. The clamps are slotted or grooved, as seen, and the attaching parts or tongues of the calks are grooved or adapted to fit onto the clamps or groovedclamp portions and to be held between the clamps and the shoe.

In speaking of calks it is of course clear that one or several calks is meant. In fact, in place of calks a continuous or one-piece calk can be applied, as seen in Fig. 5. In the latter case the attaching part of the calk is not shown grooved, but is a plain lap; but the clamps shown are serviceable for attaching either kind of calk. Such attaching part hav ing the calk portions 6 suitably extended therefrom and lapping onto the shoe, such portions form a bearing-surface, as in the case of individual calks. The continuous calk could be made of more or less flexible material to adapt itself to various shoes. The clamps, as seen, do not lap onto the tread of the shoe, but engage the upper part of same, as seen in Fig. 2. The clamps can be curved or made to arch away from the foot or into the foot, as seen in Fig. 1. The clamp thus does not touch or bear upon the foot, except, perhaps, at the points Where the clamp goes over the shoe or between the foot and the shoe. The screw 6 can have a forked part made to suitably engage or straddle the screw g.

What I claim as my invention, and desire to secure by Letters Patent, is 1. A horseshoe attachment comprising clamps arranged between the inner edge of the shoe and calks interposed between the clamps and the shoe and adapted to be secured in position by the clamps.

2. A horseshoe attachment comprising clamps and calks united or held together by tongue-and-groove connections, said calks being held or pressed by the clamps against the horseshoe.

3. A horseshoe and clamps within and adapted to sit on and press against the rim of the shoe while leaving the tread clear, and calks extended over the tread and secured or held by the pressure of the clamp against the shoe-rim.

4:. The combination with a horseshoe of clamps with oppositely-threaded screw for forcing the clamps against the shoe, a screw braced against and extended transversely from the first-named screw, a clamp held by the second screw against the shoe, and'calks held between the clamps and shoe.

5. A horseshoe attachment comprising clamps within the limits of the shoe so as not to overlap the tread thereof, and calks having attaching portions or tongues engaged by the clamps.

6. A horseshoe attachment comprising clamps with grooved portions, and calks having grooved tongues adapted to fit into the grooved clamp portions and to be held between the clamps and the shoe.

7 A horseshoe provided with calk-clamps my hand in the presence of two subscribing and with an olppositely-threaded screw for witnesses. screwing the 0 amps, a second screw made to 1 straddle the first-named screw and having a ALB RED MARTINB nut, and a second calk-clamp secured by the Witnesses: nut of the second screw.
